ROTARY non WEEDER.

Application filed March 1927. Serial No. 179,538.

My imientionlrelates lo that type of weed'- ers which employ a rotating rod that is moved sidew-isc through thc ground beneath the surtace during rotation of the rod to cut and,

mascerate the weeds. It has sometime'sbeen found diflicult to use these weeders n1 soddy ground when Certain kinds of grass have developed in cultivating the ground, or when the ground has packed too hard for the rod to lie/forced into it easily.

.lt is, therefore, the object of this invention lo provide the rod weeder with means whereby the difficulty above referred to Will be overcome and hy the use of which means this type of weccler can be employed under any rondit-ionof ground.

The result is accomplished by providing the hearing shoes with' means located adjacent. to and in Jront of the rotary rod, for ma king a horizontal cut or opening beneath the surface ol the ground in advance' of the rotary rod so that therotary rod can Colne along through the ground that has alreadyv been cut and hence not meet with as great resistanre as before.

Another object isto provide, means to asground is encountered.`

vator shoe mounted' thereon.

Figure 4 is a detail perspective view ofone f of the cultivator shoes per se.

. Figure 5 is a diagrammatic viewof a-modiication hereinafter referred to.

In the drawing 1 represents the frame of the weeder, 2 the standards, 3 the bearing shoes and 4 the rotary rod, all of Which may be of the usual construction preferably'that disclosed in Letters Patent to Henry K. Wolfe, No. 1,588,790, issued June 15, 1926.

In the practical application of the present invention .it is preferable to increase the number of standards 2 and bearing shoes 3 so as to locate them closer together than is shown in the l/Volfe patent referred to in order to reduce the necessary spread of the cultivator shoes Which constitute a part of my present invention.-

Secured to the bearing shoes3 at their front by any approved means (such as welding'or bol ting, etc.) are cultivator shoes consist-ing of upright members 5 by which the cultivator 'shoes are secured to the bearing shoes and lat-v eral wings 6 which project sidewise and rearwardly from adjacent the points of thecultiva-tor shoes to adjacent the rotary rod. lhe purpose of these wings is to make an opening in a horizontal plane just in advance of or immediately below and in advance of the rotary rod so that as the machine traverses the ground the rotary rod Will perform its functions in that port-ion of the ground which has already been cut bythe cultivator shoe.

Another purpose of the lcultivator shoes is toassist in causing the rod to enter and penetrate or bc pulled down under the ground.

B y arranging the cultivator shoes as a part of the rotaryI rod bearing unit the depth of the rod and cultivator shoes is regulated siniultaneously by lthe position oi the operator on the balancing board, and by locating the cultivator shoesas closely to the rotary rod as possible these variations of position do not cause an independent functioning of the cultivator shoes and the rod but etfect their cooperation lin such a way as to produce the result desired in the most effective Way; in other Words, by locating the cultivator shoes as close as possible to the rotary rod, the variations in depth of these members, caused by t-he change ot position of the operator on the balancing board of the machine, are such as to be practically the same at all times, thus enabling the rod alwaysy to follow through the ground which has been cut by the cultivator shoes along the plane of least resist-ance, a thing that would n ot be possible were the cultivator shoes mounted a considerable distance in front of the rotary rod or carried bya separate machine operating in advance of the weeder.

lf desired auxiliary supports 2X andncultivator shoes may be located in advance of the rod bearing standards (see diagrammatic View Figure 5).

From the foregoing description, vtaken in connection with the accompanying drawing, it is thought the complete construction, operationand advantages of my invention will lll) be clear to those skilled in the art to which it relates.

What I claim is 1. In rotary rod weeders, the combination with a rotary rod and the supportingr members therefor, of eultivator shoes having provisions for etl'ecting a horizontal cut beneath the surface of the ground in advance otl said rod, whereby the rod will pass through ground already cut, said cultivator shoes comprising upstanding supporting portions and lateral Wings projecting from the ups( andiiig portions to pass beneath the surface of theA ground in advance of the rotary rod.

2. In rotary rod weed'ers, with the rotary rod and the supporting niembers therefor, of eultivator shoeshavingprovisions for effecting a horizontal cut beneath the surface of the ground in advance ot said rod, whereby the rod will pass through ground alreadycut, said cultivator shoes comprising upstanding supporting portions and lateral wings projecting from the upstanding portions to pass beneath the surface ot the ground in advance' of the rotary rod, the Wings of one shoe extending laterally to adj acent the Wings of the next adjacent shoe.

3. In weeders of the rotary rod type, the combination with a rotary rod and its supports which includes standards and bearing shoes, of cultivator shoes secured to the bearing shoes in front of the rotary rod, said eultivator shoes having lateral wings designed to make a horizontal out beneath the surface of the ground and providing an easy path for the passage of the rod.

4. 1n weeders of the rotary rod type, the combination with a rotary rod and its supf ports which includes standards and bearing shoes, of cultivator shoes secured to the bearing shoes in front of the rotary rod, said cultivator shoes having npstanding portions and lateral wings designed to make a horizontal cut beneath the surface of the groundV and provide an easy path for the passage of the rod.

5. In w'eeders of the rotary rod type, the combination with a rotary rodand its supports which includes standards and bearing y shoes, of' cultivator shoes secured to the the combination` bearing shoes in front of the rotary rod, said cultivator shoes having lateral Wings l designed to make a horizontal cut beneath the surface of the ground and provide an easy path Jfor the passage of the rod, said Wings being so located with respect to the rod as to effect the l'iorizontal cut in a plane below the axis ot' the. rotary rod, whereby the rod will pass through the ground already loosened.

6. In rotary rod weeders, the combination with a rotar)v rod, its bearing shoes and standards for supporting the saine; ot' cultivator shoescarried by said bearing shoes in advance ol and in proximity to said rod, and iiiclud ing means to loosen the soil to enable said rod to pass through the loosened soil, said cultivator shoes including lateral blade-like extensions projected rearwardly beneath the rotary rod. i

7. In rotary rod weeders, the combination with a rotary rod, its bearing shoes and standards for supporting the saine; of cultivator shoes carried by said bearing shoes in advance ot and in proximity to said rod, and including -means to loosen the soil to enable Said rod to pass through the loosened soil,'said cultivator shoes including laterally projected Wings,

those' of one shoe extending into proximity .9. In rotary rod weeders, the combination..

with the rotary rod, of cultivator shoes, each comprising an upstandiiig central part adapted to be mounted oneasuitable support and laterally'an'd rearwardly directed blade-like extensions, the extensions of one shoe terminating in proximity to those of the adjacent shoes, and means for mounting said shoes iii advance of said rotary rod whereby said rod will pass through ground already cut.
